Vegetal bioproducts with antioxidant activity for prophylactic and therapeutic effect

Abstract

This paper presents the extractive technological process and processing of the selective vegetal extracts from the Rosmarinus officinalis L. species in order to obtain some vegetal bioproducts with proven antioxidant activity. By combining various active fractions, new vegetal bioproducts have been obtained and have been physically and chemically characterised (infrared, ultraviolet visible spectroscopy, chemiluminescence, determination of flavonoids, polyphenols, and polyphenolcarboxilic acids content) and finaly biologically tested. The antioxidant activity of Rosmarinus officinalis extracts have been evaluated by two techniques, in vitro chemiluminescence and ex vivo biological tests, both of them recommending the vegetal bioproducts for prophylactic and therapeutic purposes.
